At least we agree on the above (save for the continuing insult to my brother’s integrity and competence).
The point that some of us are trying to make is that rules (appropriately) adapted to address low fuel risks for transport category aircraft flying in and out of big people’s airports don’t work for non-transport category aircraft flying around in a third world aviation nation like Australia.
Australia already notifies thousands of pages of differences from ICAO (while maintaining the Orwellian fiction that Australia is near the top of the list of complying states - that’s how busted governments have become). A distinction between transport category operations and other operations in the domestic fuel rules won’t result in aluminium confetti.
